Specrun — questions

Answers built from our own checks of this server.

Why is there no uptime for Specrun?

Specrun runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @pavelpiha/specrun.

How do I connect Specrun?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls @pavelpiha/specrun straight from npm; nothing to host, nothing to sign up for.

Is Specrun open source?

Yes — it is published under the MIT licence, written in TypeScript and 5 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
